Origin of last motion detection event; controlled by the PIR engine.
This bit indicates how the PIR engine detected the last Motion Detected Event. When the engine sets
the Motion Detected bit in PIRStatus0, it also sets this bit according to which detection engine
registered the event.
EM Noise Detected on PIR Signal
Set by the PIR engine; cleared by the application.
• This bit indicates if the engine has detected noise on the PIR signal. This event is provided to the user
EM Transient Detected on PIR Signal
Set by the PIR engine; cleared by the application.
• This bit indicates if the Engine has detected a transient on the PIR signal. This event is provided to
Controlled by the application.
This parameter sets the minimum slope change in the signal that can be considered valid motion. This
prevents small signal changes caused by environmental or V
Use this value in combination with PIR Sensitivity and Range Control settings to balance sensitivity and
stability to the particular lens and pyroelectric sensor being used.
• Smaller values allow subtle signals with lower slopes to be considered motion events at the expense
• Larger values allow the system to ignore smaller signal slope changes at the expense of potentially
